mtd: rawnand: denali_dt: remove single anonymous clock support
Commit 6f1fe97bec34 ("mtd: rawnand: denali_dt: add more clocks based on IP datasheet") introduced a more correct binding that requires three named clocks. Now that all upstream DT files migrated over to it, remove the single anonymous clock support.
